Two missing Klein Collins High School teenagers were found after missing for nearly 48 hours.

Sophomore Alyssa Schaefer, 15, disappeared across the street from the school on Monday, and did not return home on the bus as expected. A second student, 16-year-old Noah Lewis, was also reported missing from Klein Collins High School.

Not responding, Miller says, with significant resources can have unintended consequences. When his daughter Laura first disappeared he says law enforcement treated the case as runaway. Only later did he learn she'd been murdered.

Earlier Tuesday, Alyssa's mom made a tearful plea for her return.

"Everybody is so worried about you, we want you to come home," Victoria Schaefer said. "You're not in trouble, I just want to give you a great big hug and hold you... Please be safe."
